World of Pain Mod for New Vegas

[welsh]

Hey Folks,

So I am trying to wrap up Fallout New Vegas with the World of Pain mod, and it seems I got hung up with getting into the Arena. I've managed to wipe out just about all the Tech Raiders thus far, but it seems there is a key to this door. I checked the guide on Steam but that is incomplete at best and never quite gets to this point. I think there might be 3 keys or do I need to be in a quest to get the door open? Help is appreciated.

I've played through it last year but almost everything about it is just a blur.

If I remember correctly there are 3 named Tech Raider bosses and they all have a key when you kill them.
